My dog has different bumps and soupy poop. Are they connected?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 3 years and 11 months old | 65 lbs

Over the past 36 hours my dog had developed 3 bumps, all seemingly different. One on her snout(no redness, kinda looks like a hive), one on her back (firm and had puss in it) and one on her anus, red and at the bottom. What are the odds these aren't connected, and what can be causing this?? She has normal happy temperament, eating and drinking normally. She has soupy poop, but she doesn't seem to be in any pain, even though she is usually very sensitive. Started with back then nose then anus.

That is odd and it sounds like poor Duchess has a few problems happening at one. Skin bump are generally not related unless they are occurring because of something like getting into a hornets nest or some sort of allergic reaction. Certain types of tumors can spread to other parts of the body but it doesn't generally all happen on the same day. The mass on her rectum is concerning because it is larger and very red. I recommend to have Lola examined by her veterinarian. Skin masses can be many things but red raised masses are especially concerning for a skin cancer called a Mast Cell tumor. Your veterinarian will need to collect a sample of cell to examined under the microscope to determine what this is and if further treatment is needed. Have this checked out soon.
Additionally, ongoing diarrhea often results in bacterial shifts that will continue the diarrhea regardless of the initial cause. I recommend to have Duchess examined by the veterinarian within the next 24 hours. I hope this helps and best of luck.
